The effect of short carbon fibers on rheological behaviour and mechanical properties of metakaolin-slag geopolymer binder

This study investigates the effects of short carbon fibers addition on rheological behaviour of geopolymer binder and final mechanical strength of prepared composite. The pure geopolymer binder and variously carbon fiber reinforced composites were tested. The pure geopolymer binder was synthesize...

Porous geopolymers: processing routes and properties

Cellular ceramics constitute a specific class of materials containing a high level of porosity, greater than 60 vol%, which are characterized by the presence of three-dimensionally arranged open and/or closed cells. Because of their structure, cellular ceramics exhibit a unique combination&#...

Experimental Investigation of Foams Suitable for Motorcycle Protectors

Protectors of motorcycle riders should be light and safe. This work deals with the impact test of the shoulder protectors, which differ with the use of foams of different densities. The acceleration and displacement of an impactor having the mass of five kilograms were measure...

The Biot-Darcy-Brinkman model of flow in deformable double porous media

In this paper we present the two-level homogenization of the flow in a deformable double-porous structure described at two characteristic scales. The higher level porosity associated with the mesoscopic structure is constituted by channels in a matrix made of a microporous material cons...

Numerical Assessment of Motorcyclist Accident

Road traffic accidents cause one of the highest numbers of severe injuries. Virtual human body models play an important role to assess the injuries during impact loading especially for scenarios, where complex dynamical loading is taken into account. It concerns mainly vulnerable road&#...
